Description

Propylene Carbonate (CAS 108-32-7) is a high-purity, cyclic carbonate solvent with the molecular formula C₄H₆O₃ and IUPAC name 4-methyl-1,3-dioxolan-2-one. This versatile, aprotic solvent is renowned for its exceptional solvency power, high boiling point (242°C), and low volatility, making it ideal for demanding applications in research and industrial processes. Its high dielectric constant (64.92 at 25°C) and wide electrochemical stability window (+5V vs. Li/Li⁺) render it invaluable in lithium-ion battery electrolytes. Propylene Carbonate is also prized for its biodegradability and low toxicity, meeting stringent environmental and safety standards. Available in anhydrous (≤50 ppm H₂O) and battery-grade purities (99.99%), our product undergoes rigorous QC testing including GC, Karl Fischer titration, and ICP-MS analysis to ensure batch-to-batch consistency for sensitive applications.

Application

Propylene Carbonate serves as a premier solvent for lithium battery electrolytes due to its exceptional ionic conductivity and wide liquid temperature range (-49°C to 242°C). In organic synthesis, it facilitates reactions as a green alternative to traditional dipolar aprotic solvents. The compound finds significant use as a industrial paint stripper and degreaser owing to its powerful solvency for resins and polymers. Its high dielectric constant makes it valuable in capacitor formulations and specialty coatings. Additionally, it functions as a precision cleaning agent in electronics manufacturing where residue-free performance is critical.
